capturing t.v.

[theFranchise25]

whats up...
I have an iMac that I connect to my Vizio using the miniDVI output on my mac. My question is, I have direct.v. is there a "hopefully" free way to capture t.v. from my direct.v./Vizio and save it on my iMac. Just to edit stuff for fun...????😕

you need a usb capture card like the elgato eye tv.
